I notice that when I drag images in photoshop my computer gets a bit laggy and takes awhile to render the image so its really choppy when moving them. For my specs I think my computer should be able to handle what I'm working with no problem. When I drag the image I opened up task manager and I see that the cpu use only goes up to about 25% but only one of the cpus really spikes. The memory is at about 1 GB in usage. My specs are in my sig, any idea why my computer seems to be "slacking" here?

edit: the more I think about it maybe it has something to do with my graphics card. It seems like all my windows get a bit of a lag when drag them. Theres defiantly something not right. Even a really small 72 ppi image I get huge lag when dragging and image in it. I have all the latest drivers and just reformatted so I don't what the problem is.

I don't think it happened before at least not this bad. I switch off using my mac and my pc but I would have noticed this. The temps are all normal the cpu is around 35C and the gfx is 50-55C. When I drag the images the only thing that really rises is the case temperature and its only a few degrees.

I don't really know where to check if its happening anywhere else. I know it seems like there is sometype of general lag going on, like when I minimize a window thats ontop of a window sometimes its really slow to minimize and kind of pixelates away, if that makes any sense and thats not in photoshop thats just regular windows and other programs.

I tried 2 different version of photoshop cs4 and they both had the problem. Now I'm trying cs3 and its not happening, or atleast as bad. I still see some jaggy edges as I drag objects, which is something I really shouldnt be getting with this setup. Atleast I would imagine so.
